Description

Technical Field

[0001] The utility model relates to the technical field of LCD production, in particular to a friction cloth aging structure and a friction cloth aging device. Background Art

[0002] In the production process of LCD, the alignment process is a crucial link. The alignment process is to rub and orient the PI oriented film so that the liquid crystal molecules can be arranged at a specific angle to achieve the display effect. The alignment process determines the display effect and quality of the liquid crystal display. In the alignment process, the rubbing cloth is widely used as a key tool in the surface treatment of the PI oriented film to form grooves that can orient the liquid crystal molecules. Different LCD products have different ITO lines. When rubbing, the rubbing cloth will be affected by the pattern of the previous variety after switching to different products, bringing in the difference of the previous pattern and forming a replica pattern. The efficiency of the rubbing cloth will be low and it cannot be used in continuous production. Every time a new variety is switched, a new rubbing cloth needs to be replaced, and the cost of using the rubbing cloth is high. Therefore, it is necessary to age the rubbing cloth to improve its stability and durability, which is one of the key measures to ensure the quality of liquid crystal displays.

[0003] The existing aging method of friction cloth is usually to pass the friction roller wrapped with friction cloth through the alignment equipment and perform friction aging on plain glass (i.e. white glass without patterns). Although this aging method can make the direction of the fiber hair on the friction roller uniform, it has some obvious shortcomings. First, there is no pattern on the plain glass, and the fiber hair cannot form a corresponding arrangement according to the step difference of the pattern on the array substrate or the color film substrate, which may cause poor friction during the production process and affect the yield of the liquid crystal display panel. Secondly, since the surface of the glass substrate is smooth, the friction time of the friction cloth is long, which reduces the production efficiency.

[0004] Therefore, it is necessary to improve the existing friction cloth aging device to overcome the defects of the prior art. Utility Model Content

However, this grating mechanism requires the grating to be controlled separately, and the structure and control method are complex, which is not conducive to reducing the manufacturing cost of LCD displays.

[0030] Based on this, the present application provides a structure for aging of friction cloth.

[0031] Example 1

[0032] like Figure 1-Figure 3 As shown, the present embodiment provides a friction cloth aging structure, comprising:

[0033] A base plate 1 and a friction plate 2, wherein the base plate 1 is provided with a mounting groove 11, the friction plate 2 is detachably provided on the mounting groove 11, and the friction plate 2 is provided with a friction pattern.

[0034] Specifically, the friction pattern is used to perform an aging treatment on the friction cloth, and the friction pattern can be specifically designed according to different friction cloths or different products.

[0035] The mounting groove 11 is used to accommodate the friction plate 2 and limit the friction plate 2, thereby ensuring that the friction plate 2 will not shift during the aging process of the friction cloth, and ensuring the smooth progress of the aging process. When different friction cloths need to be aged, the friction plate 2 can be removed from the base plate 1 and replaced, so that different friction plates 2 can be used to age different friction cloths, thereby improving the aging efficiency of the friction cloth.

[0036] The friction cloth aging structure mentioned above can comb the hair of the friction cloth through the friction pattern on the friction plate 2 during the aging process of the friction cloth, thereby eliminating the duplicate pattern on the friction cloth during continuous friction production, and realizing efficient and accurate aging treatment of the friction cloth. It will not affect the state of the friction cloth itself, and can improve the use efficiency of the friction cloth and reduce the use cost while ensuring the performance of the product. In addition, the friction plate 2 of the present application can be disassembled and replaced to meet the aging treatment requirements of different friction cloths, and has a wide range of applications.

[0037] Furthermore, the friction plate 2 is made of ITO glass, and the friction pattern includes a plurality of ITO grooves 21 arranged on the friction plate 2, the plurality of ITO grooves 21 are parallel to each other, and a gap d is arranged between two adjacent ITO grooves 21. The ITO glass is above 0.2 um.

[0038] The ITO grooves 21 arranged at intervals can effectively comb the hair of the friction cloth, thereby eliminating the replication lines on the friction cloth.

[0039] Furthermore, the width of the ITO groove 21 is D, 10 μm<D<20 μm, 8 μm<d<15 μm. Furthermore, it is arranged along the width direction of the friction plate 2, and the maximum distance between the edge of the ITO groove 21 and the edge of the friction plate 2 is less than 1 mm.

[0040] In actual application, the ITO groove 21 is a long strip electrode arranged on the ITO glass, the width of the long strip electrode is 10 μm to 20 μm, the gap between two adjacent long strip electrodes is 10 μm to 20 μm, and the length of the long strip electrode is 200 mm to 400 mm.

[0041] In addition, the design width D, gap d and number of the long electrodes can be adjusted according to the actual situation of the ITO glass.

[0042] In a more preferred embodiment, a method for installing the friction plate 2 on the installation groove 11 is provided. Specifically, a plurality of locking members 3 are provided on the base plate 1, and the locking members 3 are provided at the edge of the installation groove 11, and the locking members 3 include a locking plate 32 and a telescopic rod 31; one end of the telescopic rod 31 is pivotally connected to the base plate 1, and the other end opposite to the telescopic rod 31 is fixedly connected to the locking plate 32.

[0043] The telescopic rod 31 rotates, so that the locking plate 32 can enter the top of the mounting groove 11 or rotate out from the top of the mounting groove 11. When the locking plate 32 is above the mounting groove 11, the locking member 3 can lock the friction plate 2 in the mounting groove 11. When the locking plate 32 is not above the mounting groove 11, the friction plate 2 can be removed from the mounting groove 11. In addition, by setting the telescopic rod 31, the distance between the locking plate 32 and the mounting groove 11 becomes adjustable, so that different friction plates 2 can be fixed. The telescopic rod 31 of the present application is a straight rod that can be elastically deformed.

[0044] Furthermore, a push rod 13 is provided on one side of the substrate 1 away from the mounting groove 11, one end of the push rod 13 penetrates the substrate 1 and extends into the mounting groove 11, and the push rod 13 is threadedly connected to the substrate 1;

[0045] A rubber pad 12 is disposed at one end of the push rod 13 located in the mounting groove 11 .

[0046] The push rod 13 can push the friction plate 2 in the mounting groove 11, thereby changing the position of the friction plate 2, or pushing the friction plate 2 out of the mounting groove 11. Specifically, rotating the push rod 13 can change the position of one end of the push rod 13 in the mounting groove 11, thereby pushing the friction plate 2.

The setting mode between the slider 7 and the guide rail 6 can be realized by using a linear guide rail 6. Specifically, the lifting mode of the guide rail 6 can be that a cylinder is provided on the frame 5 to drive the guide rail 6 to move up and down on the frame 5.
